Home ESS with US 400A (2 x 200A Panel) Service - Lessons Learned/Current Progress

Out of curiosity (I’ll never truly grasp US power installs I guess):

  • How do you pull in a 200A line ? What kind of cable is that ?

I’ve just requested a hefty grid connection in Belgium for 2x 400V tri phase 32A.
For this feed in from the street I’m planning a cable of 4x25mm² / 3AWG (N+L1/L2/L3).
Anything above 63A is an industrial connection here (got a tri phase 400V 160A connection at the business) so 200A for a home connection really blows my fuse (pun intended).
